When does a cooling system really need a full reconditioning?


Your cooling system plays an important role in your vehicle’s performance. The cooling system helps keep your engine cool and running smoothly. A typical cooling system includes (1) a series of channels cast into the engine block and cylinder head, surrounding the combustion chambers with circulating coolant (2) a radiator, consisting of many small tubes equipped with a honeycomb of fins, (3) a centrifugal-type water pump with which to circulate coolant, and (4) a thermostat, which maintains constant temperature by automatically varying the amount of coolant passing through the system.

What to look for

It’s very important to maintain your vehicles cooling system – this will prevent more extensive repairs later.

Coolant leaks can happen anywhere  within the cooling system, if you notice any dripping on the ground or bubbling, your vehicle needs an inspection by a certified technician to make sure to stop the leak in it’s tracks and make sure no other damage has occurred.

Your coolant is most likely 50% water and it does more than just keep things from freezing. Your coolant has anti-freeze, anti-boil and anti-corrosive properties. It flows through your cooling sytsem and helps keep everything working at just the right temperature. Like all liquids, antifreeze will eventually break down and should be replaced. The system’s cooling fan circulates air through the radiator so that it can release engine heat into the surrounding air. Your fans might be mechanical or electric, and if the cooling fan malfunctions, your engine can quickly overheat.

A pressure cap is sometimes, but not always called the radiator cap. It may be on the radiator, or on the coolant reservoir. A pressure cap should be inspected at least once a year. A CAP THAT IS TAKEN OFF WHILE THE ENGINE IS STILL HOT CAN RESULT IN SEVERE BURNS from the spray of boiling coolant. The coolant reservoir indicates the level of coolant in the system. The thermostat is a valve that regulates the flow of coolant based on coolant temperature. A poorly performing thermostat can result in overheating, engine knocking, poor fuel economy, your heater not working properly, and more.
